Re: Ethernet "WAN"

I find it funny to see WAN and Ethernet in the same context considering that with multimode fiber 100Base-FX is 2km at full duplex. Even 1000Base-PX20 supports only in the vicinity of 20km-60km if you have the right lasers and fiber infrastructure. I'd call that a MAN. :)

I don't worry too much about 'broadcast' when everything is a switch these days. You need a whole lots of hosts in a single collision domain for it to start mattering. Tried to find a hub
recently? Darned near impossible unless you can pick up an old guy on ebay for $5. ;) Let's face it though, those no substitute for good architecture, no matter what technology you end up with on your WAN.

Ethernet is great for edge connects. Full duplex and switches are your friend
